Don't put words in my mouth. I'm not pretending government programs are free or private market. I'm not endorsing Medicare or Medicaid simply by acknowledging they exist.
The fact remains that tens of millions will still have government health insurance through Medicare and Medicaid if Obamacare was repealed. You're acting as if it is the end of the world as we know it if Obamacare is repealed rather than replaced with some other socialized medicine.
If someone is uninsurable because of a preexisting condition after the repeal of Obamacare, why use the force of government to redistribute wealth to cover the condition? The fact that coverage was lost because of Obamacare doesn't justify raping other taxpayers to subsidize healthcare for those who can't get coverage in the marketplace.
If anything, it seems like you're the one who is anti-free market and just loves to have Uncle Sugar loot producers to subsidize healthcare.
Regarding pre existing conditions, you misunderstand. I'm not suggesting a subsidy, I'm suggesting a reset to 2008. If people had insurance then, they should have some path to get it back. You are inadvertently advocating a massive government giveaway to insurance companies - it is classic crony capitalism. People had long term contracts with insurance companies. Obamacare broke the contracts. If you don't have an Obamacare replacement, the insurance companies are gifted new leverage to renegotiate over individuals.
